The present invention will be further described with reference to the accompanying drawings.
The invention discloses an intelligent high-altitude wiring device for an electrical test, which is used for measuring after a high-altitude wiring clamp hangs a wire and before a conventional electrical test starts, and comprises at least one wiring clamp 1, an intelligent system 2 and a control and display device 3, wherein the intelligent system is shown in figure 1; when the detection is started, a ground tester uses the control and display device 3 to send out a simple digital command, the digital command is edited and amplified through the intelligent system 2, the digital command is sent to the overhead wiring clamp 1 to start the detection command, the intelligent system 2 receives a detection signal returned by the wiring clamp 1, and after the detection signal is processed, analyzed and an intelligent judgment is given, the judgment result is fed back to the control and display device 3. Wherein:
as shown in fig. 2, the pliers 1 comprises a universal pliers and an embedded integrated system 12, wherein the universal pliers is responsible for ensuring the physical connection of the pliers jaws 11 with the connection port; the embedded integrated system 12 mainly includes a first communication module 121, a control module 122, a small pulse current module 123, an analog-to-digital conversion module 124, and a first power module 125.
The first communication module 121 is in communication connection with the intelligent system 2 on the ground, and receives a digital command sent by the intelligent system 2 and returns a detection signal to the intelligent system 2.
The control module 122 is responsible for overall control, and as shown in fig. 5, is configured to receive a detection instruction sent by the first communication module 121, control the small-sized pulse current module 123 to send a current pulse, and maintain the locked state of the embedded integrated system 12 and the pliers jaw 11 after receiving no digital instruction and completing the digital instruction, instead of operating at full time, so that the embedded integrated system 12 is in an overall dormant state most of the time, and thus normal electrical tests are not disturbed. The control module 122 adopts a 32-bit low-power-consumption ARM processor, which meets the requirements of high-speed calculation and low power consumption.
The miniature pulsed current module 123 is operatively connected to the pliers jaws 11 via a switch, as shown in figure 5, responsible for emitting the current pulses. The size of the contact surfaces of the pliers jaw 11 and the connection port, and the pressure of the pliers jaw 11 on the connection port all affect the resistance value of the contact area, and thus the returned voltage signal. The current pulse adopts a square wave type pulse waveform, the duty ratio is 50%, the frequency is 0.5Hz, the fluctuation of a returned voltage signal is small, and a detection result is easy to judge. As shown in fig. 7, the small-sized pulse current module 123 of the embedded integrated system 12 is normally kept in an off state with the pliers jaws 11, and only when the control module 122 interacts with the first communication module 121, the control module 122 controls the switch to change the small-sized pulse current module 123 from the off state to the on state or from the on state to the off state with the pliers jaws 11.
The analog-to-digital conversion module 124 adopts a 24-bit high-precision analog-to-digital conversion chip with a resolution of μ V, and is directly connected to the output end of the small pulse current module 123 without passing through a traditional amplifier circuit, thereby reducing the structural complexity on one hand and reducing the power consumption on the other hand. As shown in fig. 5, the analog-to-digital conversion module 124 is responsible for converting the voltage signal returned by the small pulse current module 123 into a digital signal, i.e., voltage data, and sending the digital signal to the first communication module 121, and feeding back the digital signal to the control and display device 3 after being judged by the intelligent system 2.
The first power module 125 supplies power to the entire embedded integrated system 12, and when the voltage value output by the first power module 125 is smaller than the preset value, it is determined that the first power module 125 is low in power, and when the power is low, the first communication module 121 sends information to the intelligent system 2, and the information is forwarded to the control and display device 3 through the intelligent system 2 to prompt the ground operator.
As shown in fig. 3, the intelligent system 2 comprises a second communication module 21, a central data processing module 22 and a second power module 23. The intelligent system 2 is used as a relay between the wiring clamp 1 and the control and display device 3, can receive and amplify the digital instruction of the control and display device 3, then sends the digital instruction to the wiring clamp 1, and can receive a detection signal returned by the embedded integrated system 12 in the wiring clamp 1, perform intelligent judgment and send a judgment result to the control and display device 3.
The second communication module 21 is in communication connection with the control and display device 3 and the wire connection clamp 1, receives a digital command sent by the control and display device 3 and a detection signal returned by the wire connection clamp 1, and returns a judgment result to the control and display device 3.
The intelligent determination is done by the central data processing module 22. The central data processing module 22 can process multiple signals simultaneously, can judge the contact state of the jaw 11 of the jointing clamp and the jointing port in each signal according to the voltage data in the returned detection signal, and feeds back the judgment result to the control and display device 3 through the second communication module 21, thereby feeding back to a tester.
The second power module 23 supplies power to the entire intelligent system 2.
As shown in fig. 4, the control and display device 3 includes a third communication module 31, a display screen 32 and a key 33, and is responsible for sending simple digital signals, receiving the judgment result of the intelligent system 2 and displaying the number of the wire holder with poor contact condition, so as to remind a field tester to adjust the connection between the wire holder jaw 11 and the wire connection port in time. The control and display device is only provided with signal transmission, receiving and display functions, has light weight and convenient carrying, and is suitable for field work of testers.
Considering the change of the application scenario, the first communication module 121, the second communication module 21, and the third communication module 31 may be wireless communication modules, specifically, WIFI modules or bluetooth modules: a 2.4G narrow-band point-to-point communication mode is adopted, so that the communication speed is high and reaches 2 Mbps; automatic frequency modulation is adopted, so that the anti-interference capability is improved, and reliable communication is ensured; a sampling-sending transmission mode is adopted, so that real-time data transmission is ensured, and no data accumulation and delay exist; and a specific frame structure is adopted, and the data frame consists of a frame header address, a data sequence number and data, so that data processing and fault judgment are facilitated. Therefore, the central data processing module 22 of the intelligent system 2 can distinguish the detection signals of the wiring clamps and give judgment respectively.
Based on the device, the invention also discloses a using method of the intelligent high-altitude wiring device for the electrical test, which comprises the following steps as shown in fig. 8:
and S1, adjusting the contact position of the jaw of the jointing clamp and the jointing port, and after the adjustment is finished, setting the embedded integrated system and the jaw of the jointing clamp into a locking state by the control module.
And S2, the control and display device sends a digital command to the intelligent system, and the digital command is edited and amplified by the central data processing module of the intelligent system and then sent to the plurality of wire clamps.
S3, after receiving the digital instruction, each wiring clamp sends a detection instruction to the control module, the control module releases the locking state of the embedded integrated system and controls the small-sized pulse current module to send current pulse to the jaw of the wiring clamp, a voltage signal returned by the small-sized pulse current module is input to the analog-to-digital conversion module, the analog-to-digital conversion module converts the voltage signal into voltage data in an analog-to-digital mode, each wiring clamp sends a detection signal to the intelligent system, the detection signal comprises the voltage data and the serial number of the wiring clamp, and the control module resets the embedded integrated system to the locking state.
S4, after receiving the detection signal, the intelligent system recognizes the wire clamp to which the detection signal belongs, judges the voltage data in the detection signal, sends the wire clamp serial number and the judgment result to the control and display device and displays the serial number and the judgment result on the control and display device, and the judgment process is as follows: if the voltage data is larger than the critical voltage value, the contact effect of the jaw of the jointing clamp and the jointing port is poor, and S5 is executed; if the voltage data is less than or equal to the critical voltage value, the contact effect between the jaw of the wire clamp and the wire connection port is good, and S6 is executed.
In the aspect of intelligent judgment, the judgment is mainly realized by judging the validity of the returned voltage data, as shown in fig. 6, if the returned voltage data is less than or equal to the set critical voltage value, the contact between the jaw of the jointing clamp represented by the signal and the jointing port is judged to be good; if the returned voltage data is larger than the set critical voltage value, the contact between the jaw of the wiring clamp represented by the path of signal and the wiring port is not good, and an instruction needs to be sent to remind a tester of timely adjustment. In addition, to improve the determination accuracy, the threshold voltage value is given by two logics: a typical voltage value according to past experience is used as a critical voltage value for judgment, at present, the typical voltage value is mainly judged by experience of testers, is the critical voltage value which is adopted in previous electrical tests of the same type and is considered to be most representative by the testers, and simultaneously, the current power industry standard is also referred; the other method is to judge according to a predicted value given by machine learning as a critical voltage value, and particularly to ensure that the critical voltage value continuously approaches to an optimal value through a result feeding algorithm of multiple electrical tests of the same type, so that the effectiveness of the critical voltage value is guaranteed. On the basis of a machine learning algorithm, a reinforcement learning algorithm in the machine learning algorithm, such as KNN (K nearest neighbor) and random forest algorithms, is adopted, although the reinforcement learning algorithm depends on a large amount of training data, testers can also or can obtain two data from a large amount of electrical tests to support the algorithm. The method starts with the correctness of the decision result, can give a more accurate prediction result after a large number of examples are learned, and has stronger universality. The two judgment logics can complement each other, and a typical voltage value given according to the past experience can be used as the basis of a predicted value given by the reinforcement learning algorithm. And dividing the time into an electrical test early stage and an electrical test later stage according to the number of the completed electrical tests, wherein the electrical tests completed in the electrical test early stage are less, and the electrical tests completed in the electrical test later stage are more. The reinforcement learning needs a large amount of data to feed, but the early stage of the electrical test does not have enough training data, so that in the judgment of the early stage, a typical voltage value based on the experience of testers and relevant electric power industry standards is taken as a critical voltage value, and the typical voltage value is more accurate than a predicted value given by a reinforcement learning algorithm; however, with the development of time and the increase of training data, the accuracy of the predicted value given by the reinforcement learning algorithm is higher and higher, so that the critical voltage value is based on the predicted value given by the reinforcement learning algorithm in the later stage of the electrical test, the dependence on the experience of testers can be eliminated, and the threshold of the electrical test can be reduced to a certain extent. In addition, different threshold voltage values are employed for different types of electrical tests. Before the electrical test is carried out, the type of the electrical test is input in the control and display device 3 by a tester, the control and display device 3 sends the type of the electrical test to the intelligent system 2, the intelligent system 2 reads a typical voltage value of the same type of electrical test preset by the tester in the system, or reads a test result of the previous same type of electrical test to train a soldier to obtain a predicted value, the typical voltage value or the predicted value is used as a critical voltage value, voltage data returned by the wire clamp 1 is judged, and the voltage data and the judgment result are stored in the intelligent system 2 for the next training.
And S5, executing the steps S1 to S4 until the contact effect of the jaw of the jointing clamp and the jointing port is good.
And S6, performing an electrical test to obtain data so as to evaluate the real-time state of the equipment and the system in the power system.
In practical application, a tester only needs to operate the control and display device 3 and send out a detection instruction through the key 33, and the intelligent system 2 can quickly return a judgment result and display the judgment result on the display screen 32, so that the tester is helped to determine the contact state of the jaw 11 of the jointing clamp and a test port and make adjustment in time.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
